LOOM-SHUTTLE.

Specification of Letters Patent.

Patented Jan. 25, 1910.

Application filed September 4, 1908. Serial No. 451,654.

T 0 all whom it may concern:

Be it known that I, DANIEL Hone BEAIRD, a citizen of the United States,residing at Alabama City, in the county of Etowah and State of Alabama,have invented a new and useful Improvement in Loom-Shuttl es, of whichthe following is a specification.

The primary object of my invention is to provide a shuttle with improvedand simplified means for facilitating the threading of the shuttle.

The invention consists in the improvements to be fully describedhereinafter, and the novelty of which will be particularly pointed outand distinctly claimed.

I have fully and clearly illustrated my invention in the accompanyingdrawings to be taken as a part of this specification and wherein Figure1 is a top plan View of a shuttle embodying my invention. Fig. 2 is aview in side elevation of the improved shuttle. Fig. 3 is a section onthe line 33 of Fig. 1.. Fig. i is a detail perspective view of thetension arm or device. Fig. 5 is a detail perspective View of the threadguide-eye or bushing. Fig. 6 is a view of one end of the shuttle withoutthe threading plate.

Referring to the drawings by numerals of reference :1 designates thebody of a shuttle of a form or type well known in the textile arts, saidshuttle consisting of an elongated wooden body having tapered ends 2, 2,provided with buffer points 3, 3, said body being formed with alongitudinally extending chamber or pocket 4: to receive the bobbin, at5, the latter being maintained within said chamber by any suitablemeans, which, as it forms no part of my present invention, I do notspecially illustrate or describe.

At the forward or let-off end of the shuttle is provided a small pocketor chamber 6 which communicates with the chamber 4 through a restrictedpassage 7. Extending through the chamber 6 and arranged transversely ofthe shuttle body is a thread guide bushing consisting of cylindricalbody 8 having external screw threads 9, by means of which it is screwedinto an opening 10 extending transversely of the shuttle. This guidebushin is cut away at its central portion within t e chamber 6, as at11, and the remaining cylindrical portion at one end is slottedlongitudinally of the bushing, as at 12, said slot conununicating withthe bore 13 of the bushing. This bushing opens through one side of theshuttle, as shown in Fig. (3, and it will be noted that the slot 1 1:opens upwardly through one of the side walls of the shuttle which formthe chamber (3.

Formed in the side face of the shuttle through which the bore of thebushing opens, is a recess 15, in which is rigidly secured a threadingplate 16, which lies substantially flush with the side face of theshuttle so as not to project therefrom, the forward end of said platebeing tapered to a point, as at 17, which point is housed behind a wall18 of the recess 15 at the forward end of the shuttle. The threadingplate is also formed with a longitudinally extending depression orgroove 20 which forms a continuation of the guide channel 1 formed inthe shuttle body.

Formed in the threading plate 15 is a thread-eye 21, which is disposedto register with the bore of the guide bushing, and extending upwardlyfrom this eye is a slot 22 of a length suflicient to clean the upperedge of the slotted portion of the bushing and at this point opens intoa slot 23 which extends forwardly to a point adjacent the points of thethreading plate. This slot 23 separates the threading plate into a lowerand upper portion, the latter constituting a horn, as at 24:, which isspaced from the shuttle a suflicient distance to permit a thread to slipeasily between the two without. catching or snarling.

Located within the chamber 6 of the shuttle body is a tension devicewhich consists of an arm 25 formed from a flat metal strip having oneend rigidly connected to the shuttle body, by a screw 26, and theforward end of which is directed forwardly over the cutaway portion ofthe guide bushing where it is fixed transversely on an oblique line anddirected downward, into said cutaway, as at 27. It will be noted thatthe lower end of the portion 27 lies in a plane substantially coincidentwith or parallel to the longitudinal axis of the shuttle, and at itslower end is formed with a thread-eye 28, to which access is had for thethread through an upwardly inclined slot 28, opening through the forward edge of said portion 27. Upon the outer face of the portion 27, orthe face away from the threading plate is an over hanging shoulder 29,which serves a purpose to be presently set forth.

The parts being as above described, the shuttle is threaded by thefollowing manipulations of the thread :-The shuttle being held in onehand, say the left one, the thread is grasped by the right hand andcarried forwardly into the space between the tension plate and the wallof the shuttle away from the support for said plate, is then turned atan angle toward the point of the threading plate, and is passed underthe point of the horn into the slot, 23, and drawn toward the slot 22and eye 21. hen the thread reaches the upper end of the slot 2-2 it ispulled down into the eye 21, which movement serves to draw the threaddown through the slot 14 in the shuttle body into the eye 15, andthrough the slot 28 into the eye 28 of the tension plate. During thethreading operation, the shoulder 29 on the tension plate serves toprevent the thread from passing up over said plate while the thread isbeing pulled through the slots in the threading plate.

It will be noted that the eye 28 in the tension plate, the bore of theguide bushing and the eye in the threading plate are in substantialalinement, and that the open end of the slot leading from said eye 28 isat a point'in advance of the said bore and the eye 21, so that thethread in being drawn into the eye of the threading plate rides down theedge of the tension device until it reaches the open end of the slot 28which permits itto move laterally into the eye 28.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent is:-

1. In a loom shuttle, a shuttle body having a bobbin chamber and atransversely dis posed thread-eye communicating with the chamber andopening through one side of the body, and a tension device located inthe body and having a transverse eye therethrough in substantialalinement with the thread-eye of the body, said tension device having aslot opening through one edge and communicating with the eye, saidtension device furthermore having a projecting shoulder on the sidehaving the slot, said shoulder being located above said slot and eye.

2. In a loom shuttle, a shuttle body having a bobbin chamber, a threadeye and a slot leading to said eye, a tension device located in saidchamber and having an eye in substantial alinement with the eye in theshuttle, and a slot leading to the eye said tension device havingdownwardly facing shoulder above the thread eye therein, and a threadingplate on the outside of the shuttle and spaced therefrom, said platehaving a slot leading from the forward edge thereof to a point adjacentthe eye in the shuttle.

3. In a loom shuttle, a shuttle body having a bobbin chamber and. atransversely disposed thread eye in one wall opening through one sideand communicating with the chamber, and a thread guide plate secured tothe outer side of said wall and having an eye alined with the threadeye, said plate having a longitudinally disposed slot having adownturned portion communicating with the top of the eye and openingthrough the front end of the plate, the portion of the plate above theslot being spaced from the wall, and means for securing the portion ofthe plate below the slot to the wall.

t. In a loom shuttle, a shuttle body hav ing a bobbin chamber and atransversely disposed thread eye communicating with the chamber andopening through one side of the body, a tension device secured to thebody and having an inturned portion that is disposed parallel to thelongitudinal center of the body and having a transverse openingtherethrough in substantial alinement with the thread eye of the body,said tension device having a slot opening through one edge andcommunicating with the eye, and a thread guide plate secured to theouter side of the body and having an eye alined with the thread eye,said plate having a longitudinally disposed slot provided with adownturned inner end communicating with the top of the thread-eye andopening through the other end of the plate, the portion of said plateabove the slot being free and spaced from the wall.

In testimony whereof I affix my signature in presence of two witnesses.
